JULES DOL'DER, OF GREVENBROICH, GERMANY.

APPARATUS FOR MERCERIZING.

SPECIFICATION forming part of Letters Patent No. 642,899, dated February 6, 1900. Application filed March 24, 1899- berial No. 710,283. (No model.)

To aid whom it may concern.-

Be it known that I, JULES DOLDER, engineer, a citizen of Switzerland, residing at Grevenbroich, in the Empire of Germany, have invented certain new and useful Improvements in Mercer Dyeing-Machines, of which the following is a specification.

This invention relates to machines for mercerizing yarn in skeins; and the object of the invention is to provide a machine in which the operations of stretching, dyeing, and washing the skeins, besides other accessory operations, will be automatically performed so as to coact to produce the best results in the finished article.

The invention consists in the improved Mercer dyeing-machine and in the combination and arrangement of its various parts, substantially as will be hereinafter pointed out, and finally embodied in the clauses of the claim.

The invention is fully illustrated in the accompanying drawings, wherein Figure 1 is a View in side elevation of my invention. Fig. 2 is a front view of my improved Mercer dyeing-machine, certain parts being removed. Fig. 3 is a view of a certain guide for imparting oscillations to one of each pair of rollers which carry the skeins, so that in the resultant oscillation of this roller the tension on the skein will be for a time varied. Figs. 4 and 4. show a pair of the rollers,a modified form of one of them for intermittently varying the tension on the skeins being illustrated. Fig. 5 illustrates hoods for closing in the skeins and the rollers carrying them while the former are undergoing the washing operation and also showing means for automatically actuating the hoods. Figs. 6 and 7 illustrate the mechanism for controlling the Watersupply and the stopping device for the machine, and Fig. 8 illustrates the mechanism for imparting motion to the rotating frame, the same being shown in top plan view.

In said drawings, g g are two uprights, which may be braced in any desired manner and which provide bearings for the main drive shaft 0 carrying drive pulleys c Mounted upon the shaft 0 is a pair of spiders (1 (1 which afford bearings for a series of stubshafts concentrically arranged therein about the shaft 0 and carrying rollers a a. In said spiders are also 3' ournaled other shafts h,which are bent into the shape of cranks and whose free ends afford bearings for other rollers b b", the other end of each of these shafts h being provided with a crank it, having a crank-pin k. Upon the inside of the upright g and adjacent the cranks h is secured a disk M, having a circular groove or slot M in its exposed face. WVith the slot M communicates another slot N, which is deflected inwardly toward the center of the disk and connects with the slot M at both its ends Hinged deflectors Q Q are pivotall y secured in an operative position at the jnnctnres of the two slots. It will be seen that as the spiders are rotated, therefore,

the crank-pins is will either follow the circular slot or the slot N, according as the deflector Q is closed or opened. It should be remarked that the deflectors Q Q may be maintained in their open or closed positions in any desired manner and that they are adapted to be manually operated.

Beneath the series of rollers there is suitably supported a tank X, adapted to receive the dyeing liquid. This liquid is fed from a siphon-pipe c communicating with a tank a which is supplied by a pump 0 said pump being operated by a lever c to which is connected a pitman o that is pivoted to and receives a reciprocating motion from a Wheel 0 which is driven from the main shaft by a system of belts 0 0 and pulleys c 0 The several parts just referred to are all shown in dotted lines in Fig. 1.

d is a suitably-fulcrumed pair of springactuated levers carrying a roller ST, the disposition of the roller relatively to the revolving series of skeins being such that as the latter approach it said roller is forced against the skeins,its function being to press or wring out as much of the free dyeing liquid as possible.

The machine is surmounted by a Washing apparatus. This apparatus consists of a pipe 61 which extends over the series of rollers in a plane contiguous, preferably, to that of their highest elevation, and a valve d controlling said pipe and supported upon a standard d", that surrnounts the upright g. The valve-stem of the valve (1 is connected to a lever d", that is fulcrumed at one of its ends in a standard (1 resting upon the top of the framework of the machine, the free end of said lever being pivotally connected to a weighted fork cl, carrying a roller (Z which bears upon the periphery of a notched disk K. The fork is guided in a bracket (Z which projects outwardly from the standard d. It will be seen, of course, that as the disk K revolves the fork will be periodically actuated to effect the opening and closing of the valve (Z controlling the watensupply. The disk K is revolved by a train of gearing K, (shown in Fig. (5 of the drawings,) said train of gear ing being connected to the shaft 0 It should be remarked that the extremity of the pipe (1 extends over the entire width of the skeins and is provided with spraying-orifices, as shown in Fig. 5. The discharge portion of the pipe may be divided, as also shown in Fig. 5, into two or more branches.

It has been already intimated that the stubshafts a a are revolubly supported in the spiders d (1 Said stub-shafts carry pulleys s, and over these pulleys extends a belt T, which also extends over a small pulley 25, that is mounted upon one end of a shaft t, journaled' in the upright g and carrying another pulley Pat its other end. In Fig. 2 the shaft '1' is shown as having a portion thereof broken away. The pulley t and consequently the pulleys t and s, which it controls, are operated from the main drive-shaft through a driving mechanism comprising the pulley u of said drive-shaft, pulleys u and u, journaled to upright g, the belt it, connecting pulleys u and it, and a belt uiconnecting pulleys u" and '6 The belt 25 is maintained taut by a tension device consisting of a weighted lever u, that is fulcrumed in the frame and whose end is provided with a roller n, which bears against the belt T under the action of the weight on the lever.

V is a stop-lever fulcrumed in the upright g and extending upwardly, where its free end is adapted to be engaged by a cam Z, disposed upon one face of the disk K. From the fulcrum end of this lever projects a detent V, which as the lever falls when released by the cam assumes aposition in the path of a projection O, which extends from the bearing of each stub-shaft a a in the spider d.

The several stub-shafts are surrounded and immediately engaged bya metallic ribbon 0, which is secured so taut that it requires some exertion to rotate the several stub-shafts in their bearings-that is to say, sufficient exertion so that so long as the spiders are free to rotate on the shaft 0 the belt will act to turn said spiders and both series of shafts they carry without individually rotating the several stub-shafts, whose pulleys, it will be observed, in effect act as practically immovable bearing devices for the engagement of the belt 25. \Vhen, however, the stop-leveris permitted to fall, so that the detent will engage one of the projections C, the spider will be prevented from rotating, and hence the belt 15 can act to rotate the several pulleys s individually.

Disposed above the main shaft 1; is the reservoir A for catching the water that falls off the skeins in the washing operation. In order to prevent the water from being thrown from the skeins over the end edges of this reservoir and down into the dyeing-tank and onto the subjacent skeins, hoods E are provided, the same being supported in suitablyfulcrumed levers A A which are connected by a pit-man A and one of which is provided with an arm A that is adapted to be engaged by a cam A upon the disk K. As the disk revolves its cam A is adapted to strike against the arm A, and thus elevate the hoods to permit the pairs of rollers carrying the skeins to successively take a position beneath them and move out from under them.

It should be remarked that the disposition of. the notch in the periphery of the disk K and of the two cams A and Z on said disk should be such that the several parts which they initially control will be made to properly coact--that is to say, said notch and the cam should be so disposed that the rotation of the spiders will be stopped and the supply of water for washing the skeins out off while the skeins are in position for the washing operation and while they are assuming this position, respectively.

The roller which I show in Figs. at and l consists of an iron body or core L, which is mounted upon the stub-shaft, and a cylinder P, having a series of longitudinal ribs upon its outer surface, which in an obvious manner effect intermittent stretching of the skeins as the-pair of rollers revolve and the skein is wound around them. This intermittent stretching of the skeins is designed to facilitate their proper impregnation with the dyeing liquid.

Assuming that the frame comprising the two spiders rotates in the direction of the arrow shown in Fig. 1, so long as the detent V does not engage one of the projections (J the beltt will act to revolve the frame and all of the skein-carryin g rollers,bringin g each skein successively under the action of the dyeing apparatus. Intermittently, as hereinbefore described, the detent V is actuated to stop the movement of the frame, and while the frame is therefore at rest certain of the skeins are being dyed, others are being brushed or scoured by the attendant, (as,forinstance,the one above the wringing 1nechanism,) others are being washed, while still others are in a position for removal by the operator, having passed through the several steps necessary to finish them. During each intermittentpartial revolution of the frame the skeins carried on the pair of rollers which are adjacent to the roller-carryin g lovers (1 are wrung out by the roller which these levers carry, so as to relieve them of as much of the dyeing liquid as possible. Of course while the frame is at a standstill, moreover, and as hereinbefore de-' scribed, the several rollers a a are being rapidly rotated, thus materially facilitating the proper performance of the dyeing-washing and other operations. It should beremarked, however, that by providing the deflected slot Nin the disk M the crank-pins can be made to oscillate the bent shafts which carry the rollers b b, so that at the point Where the skeins are removed from the machine the tension thereon will be relieved. If it is desired that each skein should pass more than once through the several operations, instead of opening the deflectors Q Q as in the case when it is desired to immediately remove the skeins, the attendant closes them, thus shutting off the passage through the deflected slot,and consequently maintaining the tension on the skein.
